[22.05] linter: allow options elements in data params

[bernt-matthias]

Linting of valid childs for params has been added here: #12232, but options for data params has been forgotten.

In addition also checks for valid attribs and filter types has been added to linting.

Questions:

• why are tools like tools/maf/interval2maf.xml not linted by the CI?

TODO

• options_filter_attribute seems allowed
• check if this is still true

  galaxy/lib/galaxy/tools/parameters/basic.py

  Line 1843 in a5c2eb8

  # only the special case key='build' of type='data_meta' is

  .. example (interval2maf suggests that also other metadata works)
• maybe doc better alternative

  galaxy/test/functional/tools/validation_metadata_in_range.xml

  Line 7 in a5c2eb8

  <validator type="dataset_metadata_in_range" metadata_name="sequences" min="2"/>

  • seems that filtering for a fixed set of metadata values is possible as well with a validator
  • but filtering for a metadata value of another input parameter is not at the moment .. maybe we should extend the validator in this respect?
